Of course, there are additional streams of revenue for Hollywood
beyond the US domestic box office. But Apple's App Store "is not
the complete revenue picture either." There's Android, for a
start. There's also "ads and services and custom development."
Once you factor all those in, Dediu expects that the app economy
will still be larger than the movie business.

The app industry is outstripping other digitally distributed
content too. It's a bigger business than TV programs, movie
rentals and purchases put together.
